How to chg Sys Colors (256 to 16bit example)

[drebhun]

I have not found an API etc. that can actually change the color palette which will allow you to change the system color resolution.

For example if I wanted to change the system color palette from 256 colors to 16bit.

I have found plenty of API's that change screen resolutiuons or the Border & Background colors:
GetSystemMetrics
ChangeDisplaySettings

Any help would be appreciated.
